IV. Core Applications (Four Main Scenarios)
1. Food Cold Chain Industry (Core Application)
Refrigerated cabinets, freezer rooms, storage of fresh meat / dairy products in food processing plants, continuous monitoring of temperature in the cold storage area
Cold chain containers, refrigerated vehicles, full-process temperature traceability during food distribution
Compliance recording in raw material cold storage, semi-finished product cold storage of food processing plants, meeting HACCP inspections by food and supervision
Direct water washing of the recorder body for cold storage cleaning, IP65 does not require removal of the recorder
2. Medical / Biological Reagent Cold Chain
Low-temperature storage / transportation of vaccines, insulin, serum, biological samples throughout the process
The coolers in the hospital pharmacy and the reagent cold storage rooms automatically record data 24 hours a day. Combined with the CFR software, they meet GMP and 21CFR regulations.
Long-term monitoring of the -20/ -30℃ reagent boxes at low temperatures, with automatic marking of data in case of over-temperature.
3. HVAC (Heating, Ventilation, and Air Conditioning) and environmental monitoring for storage areas
Continuous collection of indoor temperatures in office buildings, computer rooms, and warehouses, including air conditioning system debugging and fault tracing.
Temperature monitoring of wine and chemical raw materials in constant temperature warehouses to prevent damage to goods due to temperature variations.
4. Industrial & Laboratory Low-Temperature Testing
Long-term collection of temperature curves for small-scale low-temperature test chambers and environmental chambers.
Simple data recording for aging of electronic components and materials under high and low temperatures.
